Instructions: 1. Remove the cigarette lighter plug and insert it directly into the car socket. Start the car, then turn on the air pump switch. After the air pump starts operating, insert the air nozzle at the top of the air hose directly into the tire valve. When you hear air escaping from the tire, it indicates that the air is circulating. Tighten the nozzle to complete inflation, after which no more air will escape. 2. During inflation, the gauge needle moves with the increasing tire pressure. When the needle reaches the appropriate tire pressure (typically 2.0KG/CM to 2.6KG/CM for car tires), remove the plug and nozzle, and the process is completed.

Connect the professional ball needle, fitting, and air nozzle equipped on this device (tighten it) to inflate balls and other inflatable devices.

If you want to test the tires upon arrival, you can first reduce half of the tire pressure, or start the air pump first, and then slowly bring the tire over to tighten the air nozzle!

Instructions and usage:
1. When in use, please first start the car engine to increase power, without consuming the battery power.
2. This device is only compatible with DC (DC12V 20A) power supply; household high-voltage power supplies are not allowed. If you wish to use household high-voltage power supplies, please install a transformer.
3. When inflating, take a cooling break after working continuously for 10 minutes; this can extend the motor's lifespan. For inflatable kayaks, you can work continuously for 30 minutes.
4. For standard tires, it takes approximately 3 minutes to reach a normal pressure of 220 KPA when inflating. Larger tires require a slightly longer time. If the gauge needle rises rapidly at the beginning of inflation, it indicates that air has not been properly filled into the tire; the device must be stopped and reoperated. Otherwise, the gauge and motor may be damaged.
6. When using it, do not leave the device unattended. Always monitor the tire pressure, and avoid excessive saturation.
7. If the car cigarette lighter is not clean and non-conductive, or if the fuse is blown, the device cannot function properly. Please ensure that the cigarette lighter is conductive well.
8. This device should be protected from moisture, heavy impacts, and sand or mud intrusion. Avoid being played with by children to prevent damage.
9. The device has a high starting current; do not turn on the power switch while tires are connected, as this may cause the car fuse to burn out due to the excessive starting current. The correct procedure is to turn on the power first, wait until the air pump starts operating properly, and then connect the tires for inflation. If you need to restart the device after turning off the power during operation, remove the air nozzle before turning it back on, otherwise, the car fuse may be damaged.
Note: Some air pump pressure gauges indicate 300 PSI, but this is merely to attract attention; it is actually impossible to reach such high pressure (only 20 atmospheres). The typical tire pressure is around 2.3 atmospheres, roughly 35 PSI. The maximum pressure a typical air pump can achieve is between 7 and 10 PSI, i.e., about 100 PSI.
Instructions for use:
1. Insert the air valve at the top of the rubber tube directly into the tire valve. When you hear the tire deflating sound, it indicates that air is flowing, and tighten the air filling knob.
2. Remove the power clip; the red one holds the positive terminal of the battery, and the black one holds the negative terminal of the battery, or simply insert it into the cigarette lighter to power on the device;
3. Turn on the motor, and then you can start inflating;
4. During inflation, the gauge pointer begins to move with the increase in air pressure. When the large pointer reaches the appropriate tire pressure for the vehicle (typically 30–40 PSI), turn off the inflator switch, remove the plug, and the air nozzle.
5. Please connect the professional ball needle provided by this device with the air nozzle to inflate balls and other equipment that require air.
